Most viruses are spread through hands. In this case, using soap and hand sanitizers can solve the problem, but it can’t be perfect if there are people less concerned with hygiene. Even though most people wash their hands but if there still are a few who go around touch anything with their unwashed hands, even if they are smaller in number, we can’t prevent infection unless constantly wash our hands. To overcome this problem, we made a new door handle that spray hand sanitizer onto a hand whenever using it, which can also be sterilized itself. This product can be used in group facilities such as hospitals or schools to cut cycle of infection.
